Migraines are not infections, diseases or conditions. They are very often kinds of aches, which turn out to be stronger than headaches, and come with several other symptoms such as nausea, blurred vision, painful sensitivity to stimuli, vomiting, and in some cases even loss of consciousness. These symptoms vary from one person to another, and what they are triggered by is something many people still wonder about. Being exposed to changes in weather, certain smells or foods, or having undergone physical exertion, are said to be some of the most evident and possible causes. Some even say that the tendency of having migraines can be inherited through our genes, and that people who are more prone to getting them have certain parts in their brains that are more sensitive than others. However, there's no concrete proof for these assertions so far.
10. Why do allergies come and go?
Allergies can be difficult to live with, but some people find that theirs have unexpectedly disappeared, while others find they're suddenly suffering from one they've never had. The way this happens is a curious case indeed. Although it is scientifically possible for this to happen, we are unsure of the reason behind it. Bizarrely enough, 20% of children who have a peanut allergy lose their sensitivity as they grow older, and 80% of children who have a milk allergy lose it too by the time they reach their teens. What's more, it has been observed that the children of the present have a much larger chance of outgrowing their allergies than the children of past generations. All these facts do nothing more than stump us even more about the mysteries of this world.
